In the process of signing the contract, both parties should abide by the purpose of signing the contract, that is, standardize the rights and obligations of both parties and prevent accidents, and there is no litigation basis. Therefore, in the process of signing the contract, we must try various ways to maximize the effectiveness of the contract. Therefore, in practice, many people choose to stamp the sewing stamp in the middle of the page after signing the contract. To prove that the contract is a legally binding contract signed by both parties, and to prevent anyone from changing the middle page number.

The specific analysis is as follows:

1, because in the process of signing the contract, in some complicated cases, the contract is divided into many pages, so the inner page in the middle of a contract is easily replaced because there is no signature or handprint from both parties, so at this time, a riding seal is stamped between the pages, so that a complete seal can be restored when the page numbers are unfolded again, which can prove that the contract was signed by both parties, not replaced.

2. The function of the whole riding seal is reflected here. In addition, it is not helpful to the contract, so if you want the riding seal to take effect, you must pay attention to the position of the seal;

3. If both parties agree to use the riding seam stamp, then the edge seam must be pressed when stamping. Ordinary seals should be pressed to the signature or year, month and day of the parties, while riding seals are different and must be pressed to the seam. This seal should be evenly covered on the middle seam of the folded two sheets of paper. When it is unfolded again, the seal will be completely restored. When it is closed again, the seal is half a piece of paper, so as to achieve the effect.

If stamps are printed in this way, it can prevent some people with bad ideas from changing some contents in the middle, which will damage the rights of the obligee. If it is found that the contents have been changed in the course of litigation, and the contract has a riding seal at this time, it can be used as evidence to tell the judge that the contents have been changed, rather than the original contract party providing false certificates, and the possibility of winning the case will be greater.

I hope the above content can help you. Please consult a professional lawyer if you have any other questions.
